Kurzfassung
We apply a new probabilistic python-based high-density Particle-Tracking-Velocimetry (pyHDPTV) method and the commercial Shake-The-Box (STB) algorithm from LaVision (DaVis v10.2.0) to measured data of a turbulent RayleighBénard (RB) convection in a cubic cell. The measurement was performed in water (Prandtl number Pr = 7) with a seeding particle densities of 0,04 ppp at the hard turbulence regime with Rayleigh number Ra = 1 · 1E10. The comparison of the two PTV approaches reveals that the probabilistic pyHDPTV method leads to similar qualitative flow structures as with the state-of-the-art STB method. However, the pyHDPTV framework leads to better quantitative results such as longer track lengths, more active tracks and a higher track density over the whole measurement volume.
